Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE
Activity Summary: K?lauea continued to erupt at its summit and within the East Rift Zone, and gas emissions remained elevated. Summit inflation continued, with only slight fluctuations in lava level. At the middle East Rift Zone, the front of the June 27th flow continues to advance through forest near Kaohe Homesteads, and surface breakouts are also present closer to Pu?u ????.
June 27th Lava Flow Observations: The June 27th lava flow remains active. A Civil Defense overflight this morning observed that the flow front was moving in a more northward direction over the past day, which is a slight shift from its previous northeast direction. The flow had traveled roughly 270 m (300 yards) since Friday, suggesting that the flow advance rate may have slowed over the past several days. The flow front remains close to the boundary of the Wao Kele o Puna forest reserve and Kaohe Homesteads. The flow front is still in thick forest, creating smoke plumes as it engulfs trees and other vegetation, but fires are not spreading away from the flow.
The most recent HVO overflight was Friday afternoon. The flow front at that time was 14.9 km (9.3 miles) from the vent, measured in a straight line, and 170 m (0.1 miles) from the Forest Reserve/Kaohe Homesteads boundary. The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) was 17.1 km (10.6 miles). Between September 10 and 12 the advance rate was approximately 250 meters (270 yards) per day.
Small breakouts also remain active closer to Pu?u ????, roughly midway along the length of the June 27th flow. None of these breakouts have been very vigorous recently, but are also producing smoke plumes as they creep into the adjacent forest.
